 Dept. Agr., Office iiec. Circ. J/l, pp. 1^). — This circular contains the rules and 

 regulations for carrying out the act of August 20, 1912, a summary of which

FORESTEY. 



The profession of forestry, H. S. Graves (U. S. Dept. Agr., Forest Serv. 

 Circ. 207, pp. 17). — In this circular the author briefly reviews the rapid devel- 

 opment of forestry in the United States and discusses forestry as a life voca- 

 tion. Consideration is given to the character of the work involved, the elements 

 necessary for success, the requirements for an adequate training, the present 

 and probable future of recruits for government, state, and private work, teach- 

 ing and research work, and its possibilities as a means of livelihood. 



Annual report on the progress, literature, and important happenings in 

 the realms of forestry, hunting, and fishing for the year 1911, H. Weber 

 (Allg. Forst u. Jagd. Zig., 1912, Sup., pp. VIII+186). — As in previous years 

 (E. S. R., 26, p. 338), this supplement contains abstracts of the more important 

 literature of the various phases of forestry, together with notes on the principal 

 occurrences relating to forestry, hunting, and fishing during 1911. As in the 

 last supplement, the international scoi^e of the literature reviewed has been 

 strengthened. 



Forestry and forest resources in New York, F. A. Gaylord (N. Y. Conserv. 

 Com., Div. Lands and Forests Bui. 1, 1912, pp. 58, pis. 28). — This is a conserva- 

 tion bulletin, part 1 of which describes actual forest conditions in this country 

 and especially in New York State, and points out the harmful results which 

 have obtained through waste in exploitation and lack of protection. Part 2 

 discusses the future possibilities of the forests, outlines the principles of prac- 

 tical forestry, shows what forestry has accomplished in many other countries, 

 and what can be accomplished in this country under proper management. 



Communication on the results of the Saxony state forest administration 

 in 1911 (Tharand. Forstl. Jahrb., 62 (1912), No. 4, pp. 373-377).— A statisti- 

 cal and financial statement of the work and results of the forest administration

On the influence of removing forest litter, Schwappach (Ztschr. Forst u. 

 Jagdw., JtJf (1912), No. 9, pp. 538-558). — The author has conducted observations 

 for a great many years relative to the effect of removing forest litter on the 

 growth of trees, as well as on the character of the undergrowth and the surface 

 of the soil. The observations made in stands of pine, spruce, and beach, largely 

 during the past 12 years, are here tabulated and discussed. 



Generally speaking, removing the litter and raking the soil every year has 

 been detrimental to wood accretion even on the better classes of soil. The de- 

 crease in wood accretion was also noticeable in stands where the litter was 

 removed every 2 and 4 years. When the litter was removed only every 6 

 years, the loss in wood accretion was not great. Althougii removing the forest 

 litter every year tends to stimulate natural regeneration, it also favors the 

 growth of moss and other forest weeds. The injury to beech stands by a 

 too frequent removal of litter was quite evident in the smaller growth of the 

 leaves.
